BURNER ATTACHMENT.

Specification of Letters Patent.

Patented June 21, 1910.

Application filed September 14, 1909. Serial No. 517,685.

To all whom it may concern:

Be it known that I, THOMAS TVIOWOOM- BER, citizen of the United States,residing at Elkland, in the county of Tioga and State of Pennsylvania,have invented certain new and useful Improvements in Burner Attachments,of which the following is a specificat-ion.

This invention relates to gas burners and refers particularly to anattachment to be applied to burners which are adapted for use infurnaces or the like.

An object of this invention is to provide an attachment to a burnerwhich will cause the more thorough combustion of the gas by the peculiararrangement of the attachinent whereby a greater supply of oxygen isintroduced into the gas as it issues from the nozzles of the burners.

The invention has for a further object the provision of an attachment ofthis character which includes a solid flat member which is positioned inspaced relation about the burner and against which the flame of theburner plays whereby the same is deflected outwardly about the memberand caused to draw in an amount of air beneath the member to integrallymix with the gas being consumed and to thereby effect a greatercombustion and hence a greater heat and efficiency from the normalamount of gas consumed in the burner with the attachment removed.

The invention further provides anattachment of this character which isapplicable to burners of practically any construction and which isformed of but two disks or plates having means for spacing the sameapart and retaining the same in position.

For a full understanding of the invention and the merits thereofreference is to be had to the following description and accompanyingdrawings, in which;

Figure 1 is a perspective View of a burner having the improvedattachment applied thereto; Fig. 2 is a side elevation of the same; Fig.3 is a section on the line 33 of Fig. 2, and Fig, 4 is a top plan Viewof the lower disk or plate removed.

Corresponding and like parts are referred to in the following drawingsand indicated in all the views of the accompanying drawings by the samereference characters.

Referring specifically to the drawings in which is disclosed oneembodiment of the in vention as applied to the burner the numerals 10and 11 designate gas chambers which are opened into pipes 12 and 13 forthe introduction of gas into the chambers 10 and 11. A plurality ofnozzles 14 are extended from the chambers 10 and 11 for the purpose ofleadin gas from the same, which is to be consume The improved attachmentwhich is applied to these burners consists in a lower plate 15 which isdisclosed in the drawings as being of circular disk formation and whichis provided centrally with a diametrically extended slot 16 which, whenthe plate 15 is in position is disposed longitudinally between thechambers 10 and 11 for the purpose of admitting of the flow of airupwardly between the burners to commingle with the gas which issues fromthe nozzle 14.

The plate 15 is suitably apertured as disclosed in Fig. 4, and indicatedby the reference numeral 17 for the reception of the feed pipes 12 and13, which extend into the chambers 10 and 11. The gas chambers 10 and 11are located immediately against the upper ends of the lower plate 15 forthe purpose of preventing the passage of the air from the opening 16beneath the chambers 10 and 11. The plate 15 is provided With aplurality of standards 18, which are preferably six in number anddisposed at the opposite ends of the gas chambers 10 and 11 andintermediately of the outer sides of the same, adjacent the edge of theplate 15, as is disclosed in Fig. 3.

Upon the upper extremities of the standards 18 a second plate or disk 19is disposed which is of slightly reduced diameter to that of the plate15 and which is supported considerably above the burners or chambers 10and 11 to admit of the play of the flame from the burners 10 and 11against the under side thereof.

In use the lower plate 15 is engaged within the fire-pot of a furnace tosnugly engage with the inner walls of the same and to thereby cause thepassage of the air upwardly through the plate 15 between the burners 10and 11. This position of the plate 15 insures the intermingling of theoxygen with the gas being consumed.

In the operation of the burner and the attachment thereof the pipes 12and 13 conduct a quantity of gas into the burners or chambers 10 and 11from which the gas is permitted to escape through the nozzles 14,

which when ignited causes the flame to burn and extend upwardly from theburners 10 and 11. lVhen the plate 15 is in position beneath the burners10 and 11, which is snugly engaged against the under sides of theburners l0 and 11 air is caused to be drawn upwardly through the opening16 by the suction caused by the rising of the products of combustionwhereby the air is drawn into the flame and supplies an extra amount ofoxygen which produces a complete consumption of the gas. hen the plate19 is positioned above the burners 10 and 11 the flame from the burnersplays against the under face of the plate 19 and is deflected upwardlyand outwardly about the edge of the plate 19, thus causing a greatersuction through the aperture 16 formed through the lower plate 15. It isthus observed that during the burning of the gases a large percentage ofthe air is drawn in between the burners l0 and 11 and caused tointermingle with the gases being consumed, thereby effecting thecomplete consumption of the gases and of the production of a greaterdraft by reason of the suction formed by the flame which plays upwardlyand outwardly about the edge of the upper plate 19. Vith this burner aflame is produced which rises a considerable distance above the plate 19and which thereby intensifies the heat produced from the regular amountof gas consumed by the burner without the attachment so that aneconomical and eflicient device is produced by the application of thisattachment to burners of common formation.

Having thus described the invention, what is claimed as new is 1 1. Incombination with a pair of burners disposed in spaced relation andhaving feed pipes depending from the under sides of the same, a lowerplate engaged against the under faces of said burners about said feedpipes and having an aperture formed longitudinally of the burners andcentrally therein, a plurality of standards upwardly extended from saidlower late, and an upper plate supported on said standards over saidburners and having a diameter less than said lower plate.

2. In combination with a pair of spaced burners, a lower plate engagedagainst the under side of said burners and having an air duct formedcentrally therethrough and between said burners, and an upper platesupported in spaced relation above said first plate and having adiameter less than the diameter of said lower plate.

In testimony whereof I affix my' signature in presence of two witnesses.
